Lenovo — Bad Service after sell

Address:

Rajkot, Gujarat, 360002

After purchase from Flipkart Lenovo Vibe p1 smartphone, in 6 months it got display problem. After submitted mobile at Anil Service Center, Rajkot on 02.08.2016. They give time of 10 days, but after one month didn't repair because they have no part available from one month. No Lenovo company itself has any right information. They are saying my mobile is ready and service center is saying no part available. No any higher authority to complain because lenovo says to contact directly service center. And service center not giving satisfactory answer. It's my mistake that I bought lenovo product.
